SWITCH-LEVER.

Specification of Letters Patent. v Patented 18 Application'filed November 14, 1910. Serial No. 592,322.

To all whom it may concern:

-' Be it known that I, CHARLES A. Down, a

citizen of the- United States, residing at Watson, county of Marion, Stat West Virginia, have invented certain il jm useful Improvementsin Switch-Levers, of

which the following is a specification, reference beinghad therein to the accompanying aw nsi This invention relates to a switch lever and-particularly to a construction by which the operating lever retains the switch lever in-its shifted positions.

The invention has for an object to provide a switch stand having a pivoted switch lever mounted therein and an operating lever piv oted upon said switch lever and mounted to engage and shift said switch lever when the operating lever is shifted to the opposite limits of its travel.

Other and further objects and advantages of the invention will be hereinafter set forth and .the novel features thereof defined by the appended claims. a

In the drawingFigure 1 is a plan showing the application of. the invention to a switch; Fig. 2 is an enlarged side elevation of the switch stand; and Fig. 3 is a detail perspective of the switch lever.

Like numerals of reference refer. to like' parts in the several figures of the drawing. The numeral 10 indicates the main track rails which are provided with the switch points 11 and 12 while the switch track rails 35,.Tare indicated at 13, The switch points 11 "and 12 are connected by the bar 14 which 5 a is pivoted to one arm of a crank lever 15, the other arm thereof being pivoted to a bar-16 which is pivotally connected at 17 0 with the switch lever. This bar may be of any desired construction but is preferably formed from a plate having one end bent at a'right angle to the other at the portion 18 thereof. The switch lever 19 is mounted in the stand 20 by means of the pivot 21 and is provided at its upper end .with the sector 22 which is here shown as comprismg a slotted plate within which the operating lever .23 is disposed This operating lever 24 upon the switch with a weight 25 at is pivotally mounted at lever 19 and provided its free endin order to switch in a direction and adapted to travel.

retain itin either of its shifted positions. 1

'In the operation of the invention, with the parts in the position passage'of a train or car causes the switch stand raised to the position shown by dotted lines at 26 owing to the pressure upon the switch point 12 and as soon as this pressure is relieved, the weight upon the operating lever immediately restores the parts to the position shown in Fig. 1. If it be desired to shift the switch so that the main line tracks will be in position for use, if a car approaches from thev right of Fig. 1, the operating. lever is thrown toward the right end of the switch lever and the weight thereon, having. passed the center'of the stand 20, causes both the, switch and operating levers to be shifted to the positions shown by dotted lines at 27 in Fig. 2. This construction permits a motor and cars to run through the opposite to the points thereof without shifting the switch and obviates the use of springs for restoring the switch to its original position while securing the advantages of a yielding switch. The mounting of the switch and operating levers permits the shifting of the switch and maintains it in its shifted position so that pressure upon the switch points cannot shift the switch but a manual operation of the operating lever is necessary in order to ch'ange the center of gravity of both this lever and the switch lever-upon which it is mounted. It will therefore be seen that the invention presents a simple, eiiicient and economical form of switch lever particularly adapted for application-to mining and similar trackconstruction.

Having described my invention and set forth its merits, what I claim and desire to secure by Letters Patent is- 1. In a switch stand, a switch lever pivotthrough the switch ally mounted thereon and provided witha segmental slotted plate at its upper end, an

operating lever extended t-hrough'said plate and pivoted upon said switch lever, and means connected with the lower end of said switch lever-for operating a switch.

' 2. In a switch stand, a post, a switch lever mounted thereon and provided with a segmental slotted plate at its upper end, a switch connection from the lower end of 'said lever, and an operating lever pivoted to said and lever to be shown in Fig. W5

- switch lever above its supporting post and adapted to travel within the slotted plate carried thereby, and aweight carried by the carried thereby; upper end of said switch lever.

3. In a switch stand, a post, a switch lever i In testimony whereof I aflix my signature mounted thereon and provided with a segi in presence of two Witnesses mental slotted plate at its upper end, a CHARLES A. DUSCI-L switch connection from the lower end of said lever, an operating lever pivoted to said switch lever above its supporting post and l Witnesses:
